Using my account, I set up two households for my extended family (Home 1 and Home 2), serving two distinct groups of relatives in two different towns. Let’s call it an assisted living type of arrangement, for ease of understanding the context. My Google account is the only user account that is common to both households; no one else has accounts in both homes. I personally need access to the cameras and devices in both locations, but the other family members do not need access to each other’s business across town. In the Google Home app, the two households linked to my account are totally separate. But to my amazement, members of Home 1 who do NOT have accounts in Home 2 are able to call up Home 2 Nest Camera feeds from Home 1 via voice commands. AND THERE ARE NO SETTINGS TO REMEDY THIS INVASION OF PRIVACY ACROSS HOMES! So, despite having the facade of separate household groups for different homes, Google effectively allows non-members of household to “tailgate” through a voice command loophole that allows them to monitor private camera feeds in someone else’s house from a remote location. This kind of indifference to privacy norms in the implementation of a home monitoring system is mind boggling. There are virtually no basic privacy settings between devices and rooms, which is laughable. Anyone in the house can pipe music to your bedroom speakers at 3AM, and there’s no way to stop it. But when there is no privacy EVEN between two distinct households (different networks, different users, separated by miles), what possible sense does that make?
I have simular problem. I have three homes set up in my Google home app because I am "managing" my mothers home and my sisters home besides my own. When i am at my home and says "hey Google, turn on the lights" both my sisters lamps and my own lamps turns on (my mother doesn't have any controllable lights yet) and this is really stupid. Google should be able either by location (there is 200 km between my sister and mine home) or that the nest speaker in my sister's home only should control the lights at her home and the same with my nest. I dunno how to solve this, is it impossible for me to act as an "administrator" and have all the three homes in my home app?
Thanks for sharing details about the issue here. I know how challenging it is when there's something wrong with how your Google Home/Nest devices control your smart lights. A few questions: when did the issue start? What specific Google Home/Nest device do you have? What is the make and model of your lights? Is the issue isolated to lights only? How many accounts are linked on the Google Home app?
Please check if the same thing happen when you use the Google Assistant app on your phone.
Looking forward to your response.
